Consumption of Select Dietary Emulsifiers Exacerbates the Development of Spontaneous Intestinal Adenoma.

Int J Mol Sci 2021 Mar 5;22(5). Epub 2021 Mar 5.

INSERM U1016, Team "Mucosal Microbiota in Chronic Inflammatory Diseases", CNRS UMR 8104, Université de Paris, 75014 Paris, France.

Inflammation is a well-characterized critical driver of gastrointestinal cancers. Previous findings have shown that intestinal low-grade inflammation can be promoted by the consumption of select dietary emulsifiers, ubiquitous component of processed foods which alter the composition and function of the gut microbiota. Using a model of colitis-associated cancer, we previously reported that consumption of the dietary emulsifiers carboxymethylcellulose or polysorbate-80 exacerbated colonic tumor development.

Familial Hyperparathyroidism.

Front Endocrinol (Lausanne) 2021 25;12:623667. Epub 2021 Feb 25.

Metabolic Diseases Branch, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD, United States.

Regulation of the serum calcium level in humans is achieved by the endocrine action of parathyroid glands working in concert with vitamin D and a set of critical target cells and tissues including osteoblasts, osteoclasts, the renal tubules, and the small intestine. The parathyroid glands, small highly vascularized endocrine organs located behind the thyroid gland, secrete parathyroid hormone (PTH) into the systemic circulation as is needed to keep the serum free calcium concentration within a tight physiologic range. Primary hyperparathyroidism (HPT), a disorder of mineral metabolism usually associated with abnormally elevated serum calcium, results from the uncontrolled release of PTH from one or several abnormal parathyroid glands.
